ELECTRIC-LAMP GUARD.

Application filed February 27, 1928. Serial No. 257,331.

This invention relates to a new product of manufacture in the form of an attachment for an ordinary electric bulb or lamp socket, and it has more particular' reference to a cagelilre guard which. is adapted to house the bulb and to thereby operate as a protector for the bulb.

vVhat I have endeavored to do is to provide a product of this class which embodies as one of its structural features, shades of transparent material which surround the bulb and permit the light rays to be regulated to render the light more eifective, depending upon the nature of the work being performed.

More specifically, I propose a guard which embodies a clamp attached to the lamp socket, wherein this clamp includes a plate-like part upon which the cage is rotatably mounted, the cage being provided with a transparent colored cage section cooperable with a relatively stationary section carried by the plate.

Other features and advantages of the invention will become more readily apparent from the following description and drawings.

In the drawings:

Figure 1 is a side elevation of a lamp guard constructed in accordance with the present invention showing the approximate manner in which it is associated with the lamp.

Fig. 2 is a top plan view of the structure in Fig. 1. Y

Fig. 3 is a central horizontal section thru the cage.

Fig. il is a detail section taken approximately upon the plane of the line 4-4 of Fig. 2.

The attaching means comprises a neck 5 (see Fig. 11), which includes a suitable split resilient clamp 6 and this neck is formed integral with a circular plate 7 The cage, generally designated by the numeral 8 is rotatably mounted upon the plate. Referring to F 1 for instance, it will be observed that the plate is provided with a downturned marginal flange 9, and that the cage is provided with an inturned horizontal circular flange l0, which overlies the plate 7, and which provided with a corrugated raised annulus 11 constituting acircular retaining rack. Y

At diametrically opposite points on the plate 7, I find a pair of clips 12 having arcuate toothed portions 13 overlying and engaging the circular rack. These clips are fastened in place by small screws 14. They allow the entire cage to be turned around on the plate and to be held through the medium ofthe clips andv circular-rack in the different adjusted positions. As shown in Fig. 4l, the plate 7 carries a substantially semicircular sheet of transparent material 15 which may be green cellulose material. This constitutes one` of the half sections of vthe socalled shade.

The remaining half section is also semicircular in form as designated at 16 and thisk is carried by the relatively rotatable cagelike guard 8. In fact, I find that the guard has a central annular band portion 17 inside of which is a ring 18 fastened in place by a suitable fastener 19. These cooperate in forming a guide channel 20 as shown in Fig. 3, which permits a relative rotatable adjustment of the substantially semi-circular shaped sections 15 and 16 respectively. n

rllhe cage also includes vertical spaced parallel bar or strip portions 21.

In practice the plate 7 is attached to the socket through the medium of a neck 5 and the clamp 6 as indicated in dotted lines in Fig. 1. Thus the plate becomes relatively stationary and the cage-like guard is rotatable with respect thereto.

Hence, since one half shade is carried by the plate and the other half carried by the rotatable guard, it is obvious that the sections can be adjusted with respectY to each other to regulate the size of the opening to permit more or less light to 4become effective.

The cooperating clips and the annular racks, serve to hold the guard in different usted positions.

It is believed that by carefully considering the description in connection with the drawings, a clear understanding of the invention will be had. Therefore, a more lengthy description is regarded unessential.

Minor changes coming Within the field of invention claimed may be resorted to if desired.

Having thus described my invention, what I claim as new 1. A structure of the class described 'comprising attaching means including a clamp adapted to embrace the ylamp socket, and a cage-like bulb guard rotatably mounted on said means.

2. In a structure of the class described, a plate, an attaching neck for said plate, including a clamp, a shade forming element carried by said plate, and depending therefrom, a rotary cage-like guard mounted on said plate, and a shade forming element carried by said guard and Cooperable with said first named element.

3. In a structure of the class described, a circular plate havinga centr-al opening -surrounded by an upstanding neck, said neck being provided with a clamp, an open'evvork cagelike guard having an inturned flange at its top mounted rotatably upon said plate, a depending semi-circular transparent shade element carried by said plate, a correspond ingly shaped shade element carried by said guard and cooperable with said first-named element.

4. In structure of the class described, a

'circular plate having acentral opening sura depending semi-circular transparent shade 20 'element carried by said plate, a correspondingly shaped shade element carried by said lguard and cooperable With said first-named element, said inturned flange being provided with an annular rack, and clips carried by 25 said plate and including arcuate corrugated portions cooperable with Said rack.

In testimony whereof I affix my signature.
